Collapsible thermal container and stand

ABSTRACT

A collapsible ice chest and stand is disclosed. The ice chest has body which is defined by an outer sidewall, an inner sidewall, and an insulator between the outer sidewall and the inner sidewall, a top sealed to said body along the rim of the outer sidewall, a bottom connected at the rim of the outer sidewall opposite the top, and a pair of loop handles joined to the outer sidewall. The ice chest has pockets sized to fit over the top of the upper connector pads of the stand, by which the ice chest is supported and held in place by the stand. The stand has four pairs of crossed legs, each pair of which is pivotally connected at their approximate centers by a pivot pin. The ends of the pairs of crossed legs are connected together using connector pads, which pads are pivotally connected together and frictionally connected to the ends of the legs of the stand. When the crossed legs are compressed together at the pivot pin, the connector pads permit the cross legs to swing together into a collapsed position, whereby the collapsible ice chest is compressed by folds in the outer sidewalls, inner sidewalls, top, and bottom into a collapsed and compressed position, making the ice chest and stand collapsible and integrally foldable into a small shape that is easily transported.

TECHNICAL FIELD OF THE INVENTION

This invention relates, in general, to portable thermal containers and outdoor furniture, and in particular to a thermal container and stand, which container utilizes collapsible materials, and which stand utilizes tubular criss-crossing members that permit the stand to be collapsed and folded integrally together with the thermal container into a small shape that is easily transported.

BACKGROUND OF THE INVENTION

Conventional ice chests are commonly used items, particularly for camping, picnics, ball games, and similar outdoor occasions. Typically box-shaped containers made with inner and outer walls of metal, plastic, or other rigid material, with insulating material between the walls, and having handles on each end and a lid, which is openable, pivoting on hinges placed along the upper lip of the container along one side, ice chests are typically not foldable or collapsible, and they occupy a substantial amount of space in transport. To avoid the discomfort and inconvenience of stooping over to retrieve items from ice chests, which are typically placed on the ground at picnics and similar events, it is necessary to elevate ice chests by placing them on a table or stand. Stands upon which ice chests are typically placed, such as tables, are not very portable, and in instances where the stand is portable, the stand is much larger than is needed for simply supporting the ice chest. It is necessary to transport both the ice chest and the stand in order to have their combined benefit; and currently available stands are typically too large to conveniently transport to events such as camping trips, horse-back trail rides, and the like.

It would thus be desirable to provide a thermal container and stand that are integrally constructed to be readily assembled and disassembled without tools for use, transport and storage. It would be further desirable to provide a thermal cooler that is collapsible for ease of storage and transport and also that had its own collapsible but sturdy stand which could be conveniently transported with the thermal cooler, and upon which the thermal cooler could be supported for the convenience of persons retrieving items out of it.

A number of prior art devices have produced separately, ice chests with integral legs, stands for rigid box-shaped ice chests, and collapsible cooler bags.

U.S. Pat. No. 7,815,069, issued Oct. 19, 2010, to Bellofatto et al. describes a collapsible insulated cooler bag.

U.S. Pat. No. 7,341,164, issued Mar. 11, 2008, to Barquist, et al. describes a typical rigid box-shaped ice chest having retractable legs.

U.S. Pat. No. 6,814,333, issued Nov. 9, 2004, to Freiburger describes a collapsible stand designed to support a typical rigid, box-shaped ice chest.

None of the prior inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. All of the prior art fails to address the need filled by the current invention.

SUMMARY OF THE INVENTION

A thermal container and stand is disclosed, which container and stand are collapsible and integrally foldable into a small shape that is easily transported. When unfolded, the stand elevates the thermal container to a desired height. The thermal container is constructed with a fabric outer shell and a moisture-resistant inner lining, with an insulator between the two linings. The insulator can consist of airspace or can include insulating filler material. The top lid of the container is fixed to the sidewalls by a zipper or other fastener system. The thermal container is further constructed with exterior pockets fitted to match the upper ends of the legs of the stand, said pockets having strength to support the weight of the thermal container when fully loaded. In an illustrative embodiment, the thermal container includes a pair of strap handles mounted to remote locations along the sidewalls of the container adjacent to its top. The stand is constructed of tubular criss-crossing members that permit expansion and collapsability such that the stand can, when expanded, support the weight of the thermal container, and when collapsed can be folded integrally with the collapsible thermal container.

BRIEF DESCRIPTION OF THE DRAWINGS

For a more complete understanding of the features and advantages of the present invention, reference is now made to the detailed description of the invention along with the accompanying figures in which corresponding numerals in different figures refer to corresponding parts and in which:

FIG. 1 is a perspective view of one embodiment of a collapsible thermal container and stand in an unfolded state;

FIG. 2 is a perspective view of one embodiment of a collapsible thermal container and stand in a folded state;

FIG. 3 is an enlarged sectional view of the collapsible thermal container and stand vertical member connection.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a perspective view of the collapsible thermal container and stand 1 according to an embodiment of this invention. The thermal container 100 is shown with its top 102 in a partially open position, partially sealed with an exemplary zipper 103. The top 102 covers a cylindrical body that is defined by an outer sidewall 104, and inner sidewall (not shown), with an insulator between the outer sidewall 104 and the inner sidewall. A thermal container bottom 110 is connected at the rim of the outer sidewall 104 opposite the top 102. A pair of loop handles 111 are joined to the outer sidewall 104 at two remote locations along the outer sidewall 104. These loop handles are formed from woven webs in this embodiment, but alternatively, other types of appropriate handle material can be employed. In one embodiment, the free ends of each of the loop handles 111 are joined to the sidewall by stitching, or another appropriate attachment mechanism.

As seen in FIG. 3, ice chest 100 has pockets 112 sized to fit over the top of the upper connector pads 204 of stand 200. Ice chest 100 is thereby supported and held in place by the stand 200 attached to thermal container 100 by pockets 112.

As seen in FIG. 2, thermal container 100 is collapsible in the horizontal plane. In order to collapse the thermal container when preparing for transport or storage, a user may press the side pockets 112 or other part of the thermal container in the horizontal direction to generate the compressed profile as shown in FIG. 2.

The size and shape of a collapsible thermal container in accordance with this invention is highly variable. As shown in FIG. 1, it can be dimensioned to hold a plurality of conventional drink cans. In one embodiment, the diameter of the thermal container is approximately 18 inches. However, other diameters, heights and shapes are expressly contemplated within the scope of this invention.

As shown in FIGS. 1-3, stand 200 has a frame comprised of four pair of crossed legs 201, which in this embodiment is made from tubular members. Each pair of crossed legs is pivotally connected at their approximate centers by a pivot pin 202. Each lower end of each leg of each pair of crossed legs is connected to the lower end of a one leg of an adjoining pair of crossed legs using lower connector pads 203. Each upper end of each leg of each pair of crossed legs is connected to the upper end of one leg of an adjoining pair of crossed legs using upper connector pads 204. Eight connector pads are provided, one at each lower corner and one at each upper corner of the stand at the end point of the pairs of crossed legs. Each lower connector pad 203 is pivotally connected in one plane to the lower end of one leg of one pair of the crossed legs and pivotally connected in the same plane to the lower end of a second crossed leg of another pair of the crossed legs. The lower ends of each pair of crossed legs is thereby connected to the lower connector pads 203. Each upper connector pad 204 is pivotally connected in one plane to the upper end of one leg of one pair of the crossed legs and pivotally connected in the same plane to the upper end of a second crossed leg of another pair of the crossed legs. The upper ends of each pair of crossed legs is thereby connected to the upper connector pads 204.

The connector pads 203 are identical. As shown in FIG. 3, each pad comprises a bottom surface, a connector pin, and two extending arms. Each extending arm is sized to snugly receive the end of one tubular member of said pair of crossed legs. The extending arms of the connector pads 203 and 204 are sized to allow a pivotal connection to the crossed legs and to permit the crossed legs to swing, thereby allowing the frame to fold and unfold. When the crossed legs are compressed together at the pivot pin and the connector pads permit the cross legs to swing together in a collapsed position, the collapsible thermal container is compressed by folds in the outer sidewalls, inner sidewalls, top, and bottom

In all embodiments, the collapsible thermal container and stand folds into a compact space and can be inserted into an appropriately sized bag for transport.
